Free Stationary Waves MCQs with Answers
45 Stationary Waves MCQs from Physics, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Stationary waves form when two waves of the same frequency and amplitude travel in opposite directions and interfere. The topic covers nodes, antinodes, wavelength, phase, resonance, and the allowed frequencies on strings and in air columns. Unlike progressive waves, stationary waves do not transfer energy from one point to another.

- A. There is no net transfer of energy
- B. Energy is evenly distributed at all points
- C. Phase is the same for all points
- D. Both (a) & (b)
Explanation: In stationary waves, there is no net transfer of energy because the waves are confined, oscillating back and forth within a fixed region.
Correct answer: There is no net transfer of energy- A. Wavelength
- B. Frequency
- C. Velocity
- D. Speed
Explanation: The correct answer is Frequency. The number of loops in a standing wave is directly related to its frequency, as frequency determines how…
Correct answer: Frequency- A. 10 cm
- B. 30 cm
- C. 40 cm
- D. 120 cm
Explanation: The correct answer is 40 cm. For a string fixed at one end and free at the other, the second harmonic corresponds to one full wavelength…
Correct answer: 40 cm- A. Identical
- B. Different
- C. Any of Option A or B
- D. Stationary waves cannot be formed
Explanation: Stationary waves, or standing waves, are formed when two waves of the same amplitude and frequency travel in opposite directions along the…
Correct answer: Identical- A. 2 Hz
- B. 4 Hz
- C. 5 Hz
- D. 10 Hz
Explanation: (Remember that node to node is half A) so λ= 10/5 and then λ = 2x2=4mThen we find out the frequency using the formula v = fλ ie 20 = f(4)…
Correct answer: 5 Hz
